John, Thank you very much. Took me a few read-throughs but I get it now :) You've been a great help that is exactly what I was looking for and it all seems to work out. p.s. you were plenty clear enough just took me a while to understand the notation, it's been a while since I did calculus...

I have been thinking a little more. I said before that there are two possible angles depeding on the initial speed and that these angles converge. If I plot a graph against initial speed with the difference of the two angles I get a graph which goes from 90 to 0 with the turning points at 90...

wow thanks for the fast replies. Firstly mathguy That's right, there are two possible angles. The larger the velocity the further apart those angles are and the lower the velocity the closer those two angles are. So there is a point where "both" angles are the same, which would be the...

Homework Statement What I would like to do is find the minimum velocity needed to launch a projectile from point A to B when B is not at the same height as A. I keep finding myself stuck with two unknowns (initial speed and release angle) and I am not sure how to resolve them. If the problem...
